1 Reducing Emissions Re-enables Growth; Electronics Provides the Key Presented by : Robert Barnes Date : 2 nd December

2 The ARM Vision A world in which all electronic products and services are based on energyefficient technology from ARM, making life better for everyone 2

3 Electronics is Everywhere 3

4 Connectivity Driving The Future Mobile Internet 10B+ Units? Minicomputer Desktop Internet 10MM+ Units 1B+ Units/Users PC 100MM+ Units Mainframe 1MM+ Units 4 The Internet of things 100B+ Units

5 It s Not Just Connectivity Future driven by connectivity, software and open standards Re-use of hardware and software IP across markets ARM has the healthiest eco-system from hardware to application developers DTV, STB, BluRay, appliances Mobile computing, enterprise Automotive, smart energy The Mobile Internet 5 The Internet of things Smartphones

6 Huge Opportunity Ahead billion cores accumulated to date billion 2010 cores accumulated after next 10 yrs 2020

7 Current Big Thing : Energy Surging demand for new products and the continuing existence of inefficient products will drive energy use up Increased energy use is raising energy costs Energy efficiency will drive demand for new products Quadrillion Btu 678 Cents/kWh Total Energy Used Electricity cost Generated Electricity Oil cost Source: US Energy Information Administration, June 2010

8 Electricity is Very Inefficient 12.4% of fuel use to delivered electricity worldwide 28.7% of fuel wasted in electricity losses >50% of electricity used in motors 1000 Quadrillion Btu Electricity Electricity losses Renewables Liquids Natural Gas Coal Motors Resistive heating Others Source: Energy Information Administration (EIA), 2010 Projection Lighting Electronics

9 We Need to Start With Motors >300 million 0.75kW-375kW motors in industry generate Efficiency ~3.5GtCO2 of emissions* Motors in 2020 will cause 7% of global carbon emissions and 10% of China s emissions** Smart control can cut power consumption 25-40% 100% 90% 80% Intelligent Motor Control 60% (IMC) 50% adjusts voltage 40% to suit load. 30% Saves 5~10% 30% 50% 70% 90% power Load consumption Sources: *4E EMSA project 2008, **The Climate Group 2008, Chart is illustrative 70% Variable speed drive (VSD) controls motor to run only at the speed required. Saves 25-30% of power consumption 9

10 Similar Inefficiencies in Many Devices Servers, personal computers, power supplies, lights, Efficiency appliances, cars, show a similar curve of inefficiency 100% 90% 80% 70% 60% 50% 40% 30% 30% 50% 0 load should equal 0 power, smart devices can achieve this 10 70% 90% Load/utilization/speed

11 Design and Manufacturing Trends Past appliance design modular but inefficient 8-bit MCU ~ $1.5 HMI DSP ~ $2.0 CCU 8-bit MCU ~ $2.5 AIU This can be combined more efficiently into a single 32-bit MCU ~$2.0 HMI CCU AIU Reduction in components = cost saving Smarter design = energy efficiency Example of Whirlpool s efforts to implement lean design and manufacturing to improve product costs 11

12 The Shrinking TV 1997 Single-board Highly integrated 12 Mother & daughter boards Discrete components Heat sinks Lots of wires Limited functionality chips and I/O Advanced functionality Cool 2008

13 Focus on Software in Embedded MCU 32-bit More responsive UI Product benefits Chip features 13 Intuitive display Motor control Display driver Low power Cost effective Legacy 8- bit Device interaction Reduced energy consumption Lower component Better count & reduced connectivity product weight Faster Energy-efficient Communication operating motor control protocol stacks system algorithms

14 Standard Platform Software Advantage SW SW SW Legacy code across all company products Toolchain Fragmentation in the 8-Bit MCU market (Different Architectures by Revenue: Gartner 2006) Microcontrollers FPGA s Applications processors, System-on-Chip etc. ARM enables a single platform for embedded development Protecting investment in software design Removed 8/16/32-bit legacy It as a Software Engine Enable reuse, not just from MCU to MCU but onto other digital solutions 14

15 PCs Problem or Solution? Worldwide PC growth PC Laptop Power Netbook Cost Smartbook Time 15 continues Consuming even more power PCs are very inefficient Users don t want 100W heaters PC growth in lower power, lower cost laptops Trend towards always on Enabled by even lower power Closer to smartphones Ubiquitous computing Trend towards Cloud Computing Powered by Mobile Internet

17 Power in the Cloud Software services are driving transformation to Cloud Computing Delivering a large pool of applications Targeting all screen sizes and form factors Stimulating competition and innovation Enabled by lower power and lower cost consumer devices But what about the Infrastructure? Server farms are experiencing huge growth Communications power increasing dramatically We have to drive this power down 17
